T 0. all whom it may concern:

Be it known that we, JOHN F. OHMER and JOHN-F. OHMER, J r., citizens of the United States, .residirignt Dayton, in the county of of its running down-through the foregetful ness of the operator. It is also an object of the invention to provide means for limiting the winding movement which'may be imparted to the clock mechanism and thus prevent the clock from being overwound which might result in brealrage, or: otherwise render the clock I mechani'sm. inoperative.

. Other objects of the invention will appear as'the mechanism is described in detail.

In the accompanying drawings'Figure 1 is an end elevation of a mechanism embodying our invention; Fig. 2 is a side elevation of the same, partly broken away; Fig. 3 is a detail view of the Winding shaft; Fig. dis a sectional view taken on the line w-w of Fig. 2; Fig. 5 is a sectional view taken on the line y 1 of Fig. 4; Fig. 6 is a sectional view taken centrally through Fig. 5; and

Fig. '7 is a sectional view taken on the line .e--2 of Fig. 2.

In these drawings we haveillustrated one embodiment of our invention andhave shown the same as applied to a taximeter in which the registering devices are operated through suitable driving connections with one of the wheels of the vehicle, so long as the vehicle is moving at or above a predetermined speed and in' which the registering device is operated by a clock mechanism when the vehicle is standing still or is moving at a speed less than said predetermined speed. This taximeter is also provided with.

means for taking a record of the registration made thereby, and is provided with an op erating member which actuates the record registering device to zero. This mechanism is of a Well known character and as a whole does not form any part of the present inventrate or describe the same, and theillustrataking mechanism and also resets the trip tion and it is therefore unnecessary to illustion has been limited to the operable parts of this mechanism which enter into combi- 1 nation with the windlng devices. Itwill be understood moreover that the taX-imeter here shown has been chosen for the purposes of illustration only and that the invention may vices of various kinds.

' As here illustrated, the taximeter mocha-l nism is mounted on a base 1 having suitable be applied to clock operated registering deframe members 2 and 3. Mounted on the base is a clock mechanism 4, which may be of any suitable character, which is operatively connected with the registering device, and which comprises a winding gear 5. The mechanism is provided with an operating member, which is here shown as a handle, 6 mounted upon ashaft 7 which operates the printing device or other mechanism for taking a record of the registrations, and also serves to reset the registering counters, or apart of them, to zero. The

connection between the handle 6 and the printing and resetting devices may be of a ;well known, or any suitable, character and are unimportant so far as the present invention is concerned, it being only necessary that the function of the handle 6 be such that it will be operated with more or less fre- 6 has a geared connection with the winding mechanism of the clock 4 and, as here shown a pinion 8 is mounted on the shaft 7 and rigidly connected with the handle, and

meshes with a gear 9 which in turn is connected throughan idle pinioriJO withjagear 11 mounted on a shaft 12. Connected with the shaft 12 isa pinion 13 which is connected through an idle pinion 14: with a pinion 15 mounted on a shaft 17 to which is secured a beveled pinion 18 meshing with a beveled pinion 19 on the winding shaft 20,

which is journaled on the base 1. and is provided with a pinlon 21 which meshes with the gear 5 ofthe clock winding mechanism.

Consequently each operative movement of the handle 6 will transmitwinding move- I ment to the clock mechanism. The particular arrangement of gearing here shown has been designed to adapt the mechanism to the -.quen'cy. This handle, or operating member, i

taximeter which we have illustrated but it will be understood that the geared connection between the handle and the winding shaft may be of any suitable form or ar- .sleeve portion, 22 provided with V-shaped teeth which cooperate with similar'teeth on a second sleeve, or clut'ch member, 23 which is slidably mounted on the shaft 20 but is held against rotation thereon by means of a pin 24v mounted in the shaft 20and extend-- ing into a longitudinal slot in the sleeve 23. A spring 25 is confined between the slidable sleeve, or clutch member, 23 and a fixed part, such as a collar, 26 .on the shaft and tends to hold the slidable clutch in operative engagement with the hub, or clutch member, carried by the beveled pinion. sion of the spring 25 is such that the clutch members will normally be held in operative engagement and the shaft will rotate with the beveled pinion, but when the clock mechanism has been substantially fully wound the resistance to the rotation of the winding shaft will overcome the-tension of the spring 25 and the clutch member 23 will slip and permit the teeth of theclutch member-on the. beveled pinion to ride over the teeth thereon, thereby permitting the movement of the beveled gear and the train of gearing connected therewith without imparting further winding movement to the clockmech-' anism.

It may also be desirable in some mechanism to operate the clock windin 'device from the mechanism which drives t 1e registermg'devlce from the wheel of the vehicle and we have here illustrated means for ac-[ complishing this result in conjunction with the operation of the winding mechanism from. In the present mech the operating handle. anism the registering device is operating from the wheel by means of a shaft 27 and we have geared this shaft with the shaft 17 whichcarries the beveled gear 15, this being accomplished by means of beveled gears 28 and 29 so that the rotation of the shaft 27 will be transmitted through the shaft 17 to the winding shaft 20. In order that the winding shaftmay be operated from either source of power without interference from the other source of power we have connected the driving shaft 27 and the handle 6 with the beveled gear.

The tenthe shaft 17 through suitable overrunning clutches which will cause the shaft to rotate.

with either source of power but will permit the shaft to rotate independently of either source-of power. As shown in Figs. I, 5 and 6 the beveled pinion 29 has secured thereto a disk 30 which carries paiwls 31 which are held normallyin engagement with aratchetgwheel 32 rigidly secured ,to-the shaft 17 and will consequently cause the shaft to rotate with the beveled gear but will permit the shaft torotate independently of Likewise as shown in Figs. 2 and 7, the gear 11 is loosely mounted on the shaft 12 and carries nawls 33 which engage a ratchet wheel 34 rigidly secured to a sleevev 35 which is also rigidly secured to the gear 13. Thus the rotation of the gear 11 will impart rotation to the ear 13 but the gear 13'is free to rotate independentlyof the gear 11. Consequently the winding shaft 20 can be actuated from either source of power-without interference with or from the other source of power. The winding shaft 20 is preferably provided with a squared head, or end portion; 36 to receive a key by means of which the lock mechanism may be woundindependent y of the registering; device and its cooperating parts. I
